As the Astral Express crew lands on Penacony, they’re greeted by Honkai Star Rail’s Sunday – one of many vibrant characters working to get the Charmony Festival up and running. We first saw him in the 1.6 livestream ahead of Penacony’s release, and now he’s with us on the Express as an excellent teammate.
It’s a perfect time to dive back into the game, and there are plenty of Honkai Star Rail codes to redeem. Here’s the current Honkai Star Rail banner, and what you can expect in the next Honkai Star Rail update.
Here’s everything in our Honkai Star Rail Sunday build:
What is the best Honkai Star Rail Sunday build?
Sunday follows the path of the Harmony and uses the imaginary element.
| Best light cone | A Grounded Ascent |
| Light cone substitute | But the Battle Isn’t Over, Past and Future |
| Best relic set | Sacerdos’ Relived Ordeal |
| Planar ornaments | Lushaka, the Sunken Seas |
| Main stats | Body: crit damage Feet: speed Planar sphere: HP/def Link rope: energy regeneration |
| Sub-stats | Crit damage, speed |
Sunday is a truly excellent support character in Honkai Star Rail, who can seemingly do everything. The best light cone to equip him with is his signature, A Grounded Ascent, with a set of Sacerdos’ Relived Ordeal relics. As for planar ornaments, we recommend Lushaka, the Sunken Seas, but you can also use Broken Keel.
You can use Sunday alongside pretty much any DPS in the game, as he provides damage boosts and energy regeneration, with a hefty crit boost. He’s best for Jing Yuan, however, as his kit also works with summons, which includes the Lightning Lord and Topaz’s trotter Numby.
What are the best light cones for Sunday?
The best light cone for Sunday is his five-star signature, A Grounded Ascent. You can also safely use Bronya’s signature, But the Battle Isn’t Over, as both cones boost both Sunday and your team’s performance when using his ultimate and skill on allies.
Now, if you want to make a full imaginary team, you can use the Planetary Rendezvous light cone to make use of it’s unique buff.
| A Grounded Ascent | After Sunday uses his skill or ultimate on an ally, he regenerates six energy, and the ability’s target receives one stack of Hymn for three turns, stacking up to three times. Each stack of Hymn increases its holder’s damage dealt by 15%. After every two instances of Sunday’s skill or ultimate he uses on one ally character, he recovers one skill point | Light cone banner |
| But the Battle Isn’t Over | Increases Sunday’s energy regeneration rate by 10%-18%, and he regenerates one skill point when using his ultimate on an ally. This can trigger after every two uses of his ultimate. When Sunday uses his skill, the next ally taking action deals 30%-50% more damage for one turn | Standard and light cone banners |
| Past and Future | When Sunday uses his skill, the next ally taking action (except the wearer) deals 16%-32% increased damage for one turn | Forgotten Hall store |
| Planetary Rendezvous | After entering battle, when all allies deal imaginary damage, the damage dealt increases by 12%-24% | All banners |
What are the best relics for Sunday?
Though he’s not a damage dealer, bringing up Sunday’s crit damage is important to boost his ultimate effect, which adds to your chosen target ally’s crit damage.

| Messenger Traversing Hackerspace | Two pieces: Increases speed by 6% Four pieces: When Sunday uses his ultimate on an ally, the speed for all allies increases by 12% for one turn. This does not stack |
Cavern of Corrosion: Path of Elixir Seekers on the Xianzhou Luofu |
Planar ornaments
| Lushaka, the Sunken Seas | Increases Sunday’s energy regeneration rate by 5%. If he is not the first character in the team lineup, then the attack of the first character in the lineup also increases by 12% | Divergent Universe reward |

What are Sunday’s abilities?
Active skills
| Basic attack | Deals imaginary damage to one enemy based on Sunday’s attack stat |
| Skill | Enables one target ally (and their summon) to take action immediately. Their damage also increases. If the target has a summon, the damage increase gets further boosted for two turns. After using his skill on The Beatified target, Sunday recovers one skill point. When he uses his skill on a character on the Harmony path, the immediate action will not occur |
| Ultimate | Sunday regenerates energy equal to 20% of the max energy to one target ally. This also turns them into The Beatified. Their crit damage increases based on Sunday’s crit damage plus a percentage. At the start of his turn, the duration of The Beatified decreases for one turn and lasts for three overall. The effect dispels if Sunday gets knocked down |
Talent
| The Sorrowing Body | Increases the crit rate of a single target ally for three turns |
Technique
| The Glorious Mysteries | The first time Sunday uses an ability on an ally target, the target’s damage increases by 50% for two turns |
Traces
| Rest Day’s Longing | When using his ultimate, if the energy he regenerates is less than 40, it automatically increases to 40 |
| Exalted Sweep | Sunday regenerates 25 energy at the start of the battle |
| Haven in Palm | Sunday dispels one debuff from the target |
What are Sunday’s eidolons?
| E1 | When using his skill, the target ally ignores 16% of the target enemy’s defense to deal damage. Their summon if they have one, ignores 40% of the defense stat. These both last two turns |
| E2 | After using Sunday’s ultimate for the first time, he recovers two skill points. The damage by The Beatified increases by 30% |
| E3 | Increases the level of Sunday’s ultimate by two, up to a maximum of 15, and his basic attack by one, up to a maximum of ten |
| E4 | When a turn starts, Sunday regenerates eight energy |
| E5 | Increases the level of Sunday’s skill by two, up to a maximum of 15, and his talent by two, up to a maximum of 15 |
| E6 | The crit rate boost of Sunday’s talent becomes stackable, up to three times. The talent’s duration increases by one. When using his ultimate, Sunday can apply the talent’s crit rate boost to the target, as well. When this takes effect, and the target’s crit rate exceeds 100%, every 1% excess increases their crit damage by 2% |

Who is HSR Sunday?
Sunday is an organizer of the Charmony Festival taking place on Penacony and is a representative of the Family – a group that follows Xipe, the Aeon of the Harmony, and includes the Bloodhound, Iris, Oak, Nightingale, and Alfalfa divisions among others.
We learn plenty about Sunday during the course of the Charmony Festival and the Trailblazer’s adventures in Penacony, including his true reason for heading up the Family and representing the festival. No spoilers, though – you’ll have to play the game to find out for yourself.
A few different species are name-dropped in the 2.0 updates, including the Halovians, of which Sunday is one along with his sister Honkai Star Rail’s Robin. They both have small wings close to their ears and have a halo of sorts above or behind their heads.
Need a hand building up a team? We’ve got you. Here are the best builds for Honkai Star Rail’s Welt, Honkai Star Rail’s Gepard, Honkai Star Rail’s Qingque, and Honkai Star Rail’s Lynx to get some good damage and protect your teams.
